- Аннотация: The technology of drilling slant exploitation well in the oilfield ofWestern Siberia has been studied. Development of well constructionhas taken into account the next geological features of the section:permafrost rocks occur to the depth of 260 m, and iciness also takesplace. Well construction is selected on the base of intervals ofincompatible drilling conditions. The designed profile includesseveral intervals: one vertical interval, one zenith angle buildupsection, two hold sections and one zenith angle drop section. Acheck calculation of the setting depth of the intermediate casing forthe condition of preventing hydraulic fracturing of rocks near theshoe was carried out, and the safety factor of rocks for hydraulicfracturing was found. Drill pipes calculation includes determinationof their length and diameter as well as allowable setting depth fordrill pipes. This article demonstrates drilling methods, boreholeunder-reaming methods and the main parameters for theperformance of technological operations of directional drilling. Adrilling rig has been selected according to the allowable hook load.The density of the used drilling muds has been substantiated for theintervals of compatible drilling conditions, types and parameters ofmuds
